Description
General part information
TPS25221 Series
The TPS25221 is intended for applications where heavy capacitive loads and short circuits may be encountered. The programmable current-limit threshold maybe set between 275 mA and 2.7 A (typical) using an external resistor. ILIMITaccuracy as tight as ±6% can be achieved at the higher current-limit settings. Power-switch rise and fall times are controlled to minimize current surges during turn on and turn off.
When a load attempts to draw current exceeding the programmed ILIMITthe internal FET enters constant current mode in order to keep ILOADat or below ILIMIT. TheFAULToutput will assert low during over-current conditions after the built in de-glitch time.
